Other than winning a dec over Cro Cop...right after CC was headkicked into mediocrity, Kongo's best win ever is probably Paul Beuntello.

If he had Roy's Physique he would have been out of the UFC already and would have very few fans.

He wrestled the terrible grapplers. He wall and stalled the weaker fighters with decent striking. He got out-struck and KO'd by the good strikers. People like to call him a striker, but I saw far more wall and stall/wrestling attempted from him than I saw striking clinics.

When he fought Yvel he was lit up. When he fought Barry he was lit up until he found a hail mary KO that Pat ran into. When he fought Hunt and Roy he never had a chance standing.

Kongo won a lot of fights because they repeatedly gave him the likes of Dan Evenson, Al Turk, Paul Beuntello, Shawn Jordan, Assuerio Silva.

yes, but still, GSP's french enough to be a great draw in France, trust me. Everybody knows GSP here and everybody tunes in to watch him fight.

He's way more of a draw here than Kongo ever was

and I don't see any other french in the UFC drawing more viewers as for today than GSP

Actually I couldn't even name all the french guys in the UFC right now aside of Kongo, the only french MMA fighter whose name comes to mind isn't in the UFC, it's Xavier Foupa-Pokam who fought in the UFC a while ago, lost twice, got cut and now he's in other orgs.

Tarec Saffiedine is actually from belgium, depending on how he fares in the UFC, he could potentially be a draw too, but it's a fairly long shot to imagine him fighting for the title. He got a nice record, stats wise, but hasn't really fought anybody relevant aside of Nate Marquart.
